Nitrophyl Float Center Pivot

The Nitrophyl Float Center Pivot is a precision carburetor float engineered for Holley and Quick Fuel Technology carburetors used in marine and boating applications. After years running engines on the water, any boater knows that fuel delivery consistency directly impacts throttle response, idle quality, and overall engine reliability in demanding conditions. This center-hung float design maintains precise fuel bowl levels across varying sea states and operating angles, ensuring your engine receives a stable fuel supply whether you're cruising flat water or navigating choppy conditions.

Constructed from nitrophyl material, this float offers superior durability and chemical resistance compared to traditional brass or cork alternatives, preventing fuel absorption and dimensional swelling over extended service life. The center pivot mounting configuration balances load distribution evenly, reducing wear on the needle and seat assembly and extending carburetor longevity. Nitrophyl's lightweight properties minimize inertia effects during rapid trim changes or heavy acceleration, allowing the float needle to respond quickly and accurately to fuel demand—critical for maintaining lean cruise efficiency and preventing rich stumbling during deceleration.

This float is ideal for boaters running vintage or modern Holley and Quick Fuel carburetors on inboard, outboard, or performance marine engines. Installation is straightforward for anyone comfortable with basic carburetor service; simply remove the float bowl, detach the worn or damaged float, and install the new Nitrophyl Float Center Pivot using the existing pivot pin. At 0.06 lbs and compact dimensions (5.05 x 1 x 5.3 inches), it fits standard carburetor cavities without modification. Whether you're restoring a classic boat engine or maintaining a current-generation fuel system, this replacement float delivers reliable fuel control and proven compatibility across multiple carburetor generations.
